While the present invention is herein illustrated as embodied in a conventional form of addressing machine, it is to be understood that it is not so limited, but may be readily adapted for use inr conjunction with other forms of imprinting apparatus, including tabulating, billing and check writing machines, typewriters and other analogous mechanisms wherein it may be advantageous or desirable to differenti-ally feed superposed strips of continuous series connected form stationery and imprint thereon simultaneously at different spaced intervals of the respective strips.

The imprinting apparatus illustrated, and commercially known as, an Addressograpn comprises a stand or legs l supporting a table 2, from which projects a vertical magazine 3 containing a stack of legend determining elements 4, which plates or stencils. In

which the present registering and aligning feeding mechanism also may be utilized, suck legend determining elements ordinarily comprise consecutively fed from a suppl: thereof and which control the setting of the impression by means of transfer material.

"ied by a reciprocatory slide 5, automatically actuated-in properly timed sequence by a connecting rod S and crank l," motorv actuated through a pulley and belt speed reductiontrain 8, all located beneath the table 2,. The printing -plates Il are advanced singly from the magazine and consecutively presented in imprintingposition beneath the depressible pressure head il and in" impression imparting 'relation with successive portions of continuous superposed 'strips of record material lll and Il.

The present embodiment of the invention is designed for imprinting upon a succession orseries connected checks or other forms, consecutive identifying numbers or other indicia and the naine, address, account number, or other personal data, and to simultaneously imprint upon a master or detail sheet the same check or form number the same data. rrothis end the record strips itl and il, which may be the saine or different widths, as desiredare advanced from supply compartments i2 'and it bel-our table-2 at the front of the apparatus, 'from which the respective strips areY directed past separate nuinher imprinting units is and l5, fhich may be oany, conventional construction and of which numerous forms are available upon the ,market These numbering units are actuated by suitable connections with the operating parts of the imprinting apparatus. f

Beyond the respective numbering units Hl and I5 the record strips pass in superposed relation onto the table ci the Addressograph machine.

As a convenient and economical 'n method or manifolding the imprinted legend ordata, a continuous strip of Carbon or transfer material Yis preferably interolded Withrthe supply of record material H, which comprises Vthe slower moving strip and upon which is nianiiolded the in'lprinted legend or data.

Obviously, ii so desired, one of the numbering units may be so located 'as to'irnprint upon 'the superposed strips and produceV its seco-nd imthe interposed carbon or In their rearward course, over the top of the table 2, the superposed record-strips it and H pass the imprnting position beneath the pr eser head land immediately beyond such portion they are simultaneously engaged by separate pin type feeding devices 55 and l'l' engageable in inarginally punched holes in the record strips and simultaneously actuated through movements of diiierent extent to diierentially advance the record strips lil and il. The original'record strip, which may comprise a succession o t checks or other forms, is advanced a full form length at e each. operation to presentthe prescribed area of the succeeding form in imprinting position, while `the Underlying duplicate or master strip is advanced a lesser distance Vsuiilcient to receive the maniiolded imprints in closely spaced'succession.

The feeding units EPB and ll may be of'aiiy suitaile type, but for 'lustrative purposes have been sho-wn as rotary pin Wheels having radially dispo-sed pins l? engageable in marginally punched holes lil in the record strips Il) and l i. Obviously, other iorrns of traveling pin type devices serving like purpose may be substituted therefor. The pin Wheels it and il are carried by transverse rotary shafts 2t and 2l, supported in a super- I receiving compartment 2e, and supp rte:

structure mounted upon the imrfmtnsapparatus table and comprising opposite end ramesiu `and 2 3 interconnected by sundry tie rods.

Mountedv in the super-structure in velevated relation above the respective feeding devices i6 and Il are elevating devices 2.5 and 2t, one for each strip or set of strips, carried on transverse rotary shafts 2'! and 28 `journaled in the superstructure end frames 2 2 and 23, which are 'differentially actuated inlunison with the 'correspending Strip feeding device. These elevator devices are also pretereplyZ although necessarily, of the pin type having engagement in the marginal` feedrnclea but are so adjusted rotatiyely relative to the feeding devices EG and il that there is a slight degree of slackness in the strips between the feeding and elevator devices and the latter do not exert any pulling feeding inriluence other than to lift the imprinted portions of the strips and propel them on their way-to separate receivers. The original record strip I0 is received in a compartment or tray supported in elevated relation above the imprinting -lull@- ratus table 2 and somewhat below the level or its elevator into which the strip l@ is reolded upon its original fold lines. A t the saine time, the duplicate strip l l is directed oy its elevator Eli-onto an inclined elevateddeel bene-.th the rear end substantiallycoincident with til; under Drag:

Mediallyof thestub shaft 45 is a broad fated peripherally notched Wheel or disc 9, Which frotates in unison ,with the drive pulley in a plane closely adjacent to the larger timing disc 4S, but normally independently thereof.

The pulley 38 and with it the peripherally notched Wheel 49 are continuously driven by the motor `35' and are intermittently connected with either one or both sets of pin type strip feeding and elevating devices by single operation coupling means adapted to actuate the driven mechanism through a predetermined range of operation and at the end thereoi eiect automatic disengagement of the driving means. -Pivoted to is xedly mounted a'relatively'large timing disc land smaller discs 48 and 9.

the face of the larger disc 48 is a spring pressed pawl or dog 5having a square nose engageable in any one of the several square notches in the periphery oi the wheel or smaller disc 49 to operatively connect the larger disc for unison rotation.

In Figs. 12 to 16 there is illustrated timing mechanism to accurately time the engagement and disengagement of the driving and driven mechanism and the duration of the period of operation. To engage and disengage the drivingr dog 55 with the notched driving Wheel or disc 49 at timed intervals, a pair of arms 5l and 52 are freely pivoted on a stud 53- and disposed respectively in the planes of rotation of the larger Each arm 5I and 52 is provided with a retractile spring 54 connecting studs in the free ends of the respective arms with a stud 55 on the frame 23. The arm 5I carries on its under side a roller 56 which rides on the periphery of the disc 48 during rotation of the latter, and which drops into a peripheral notch 51 in the disc at the limit of each operation. The arm 5I is further provided with a lateral iinger or lip 58 which extends beneath the companion pivoted arm 52 and serves to lift the latter arm 52 in unisonV with elevation of the arm 5i. The arm 52 extends rearwardly of its pivotal stud 53 and is connected by a link 59 with the core of a solenoid or armature of an electro-magnet `l5!) mounted at the rear of the super-structure. This operating link 59 extends through a transverse opening in a boss El projecting from the inner side of the frame 23 immediately above the electro-magnet E5 and which supports a guide roller 6l' about which the record strip I passes in its course from the feed device I6 to the elevator 25.

The driving pawl or dog 55 pivoted to the disc d3 is formed with a shoulder 52 into the path of which the free end of the loosely mounted arm 52 projects when in its depressed position. The engagement of the shoulder 62 with the end of the arm 52 as the driven mechanism approaches the limit of its range of movement, causes the dog to be cscillated out of engagement with the peripherally notched wheel or smaller disc i9 against the yielding resistance of its spring 63, to thereby disengage the drivingand driven mechanism.

' This engagement of the shoulder 62 with the e-nd of the pivoted arm 52 positively arrests the rotation of the disc G8 and with it the driven mechanism. The disc completes a full rotation at each operation and the mechanism is simultaneously actuated through a complete cycle to advance the original record strip a full predetermined form length, and correspondingly advance the duplicate strip for whatever length the mechanism may be set. However, it is desirablev to sometimes issue split tickets, or forms of fractional length. To do so the arms 5i and 52 are duplicated in reverse relation at 5ian'd 52at the lower sideof the disc 68 where-they operate in like manner to arrest the operation when the disc has made but a hahc rotation, by engagement of the roller 55 in the notch when the latter is in the lowermost position. The Varms 5l and 5I are interconnected byV a link 59 for unison operation under influence of the link 59 and electro-magnet 5d to initiate the cycle ci operation, Whether ofV full or half rotation of the disc 49. YWhen full form feeding is desired and complete rotation of the disc 48 effected, the supplemental arms 5i and 52 are locked iii) out of operative relation by a cam lever 60a. This is permitted by a slotted connection 60h of the link 59'.

To release the driving dog or pawl for reengagement with the notched driving wheel or disc 49, an electric circuit is closed through the solenoid Vor electric magnet 60 in timed relation with the operation of the imprinting apparatus.A In the conventional Addressograph construction, in association with which the present invention is illustrated, the swinging presser head 9 is providedvwith small rollers 9a to which is imparted a to and fro motion while the presser head isln depressed position. This motion is transmitted to the rollers by a curved bar 64 in Figs..20 and 21, located closely adjacent to the oscillatory presser head 9 and having differential motion incident to the swinging motion thereof. This diierential motion of the bar 64 incident to actuation of the presser head during the imprinting operation of the Addressograph is utilized to trip successively electric Switches controlling the electro-magnet circuit and also that actuating the numbering devices.

A stud S5 is mounted on the roller operating bar 64 of the presser head and incident to the operative movement of the head such pin describes a circuitous path of travel indicated by dash lines and arrows in Fig; 4 and Fig. 20. While the stud 55 may be mounted directly on the .bar 64, since the present apparatus is applicable to existing Addressograph machines, the stud 651s preferably carried by a U shaped clamp 65 which straddles the bar 54 and is releasably secured thereto.

Mounted c-n the end frame 23 are two lever operated electric switches 65 and El (see Figs. 4, 5 and 11), having oscillatory operating levers 68 and 59 which extend into the path of travel of the tripping pin or stud 65 carried by the roller actuating bar 54 of the presser head S.

The electric switch @S controls the operation of the numbering devices if and l5, with which it is connected through the cable 5 These numbering devices, as well as the electrical switches, may be of any suitable or conventional construction, of which there are several different commercial forms available. The numbering devices embody electrically energized operating means (not shown) which upon closing of the Aelectrical circuit by oscillation of the switch arm 68 incident to engagement therewith of the stud 65 effects consecutive numerical imprinting of the respective record strips. After operating the numbering control switch, the stud 55 by its continued travel engages and operates in sequence the lever GS of the electro-magnet control switch 61 to close the circuit through the magnet 5G. The energization of the electromagnet and resulting attraction of its armature acting through the link 59 oscillates the pivoted ann 5i, raising the front end thereof and lifting the roller 5G out of the notch 5'! in the periphery of the disc 48.. The same movement of the arm 5i effects elevation of the companion arm 52 yout of engagement with the shoulder 62 of the driving dog 5D by the lifting engagement of the lateral finger or lip 58 therebeneath such lever 52.

The driving dog 5! upon release by disengagement of the end of the arm 52 vfrom the shoulder 52 permits the dog 5@ to engage the notched wheel 49 under influence of its actuating spring. In event the supplemental split ticket or fractional form control levers 5| and 52 are released from their locking device, they are actuated in unisor with the levers i and 52. So long as the rollers 56 and 5S' ride upon the periphery of the rotating disc 48, thereby holding the arm 5I elevated and arm 5| depressed, the companion arms 52- and.

52, Will also beheld out of the path of the shoulder 62 of the dog 5ft.V When the disc has com- Dleted a prescribed degree of rotation, either full rotation or a predetermined partial4 rotation, the descent of the roller 56 or 56.' into the peripheral notch Sliunder influence of the retracting spring 54 again presents the end of the arresting arm in the path of the shoulder, 62 of the dog and the latter is again disengaged; The disc 48, is thus actuated through a full rotation, a half rotation or ctherpartial rotation, according to the length of .split forms to be fed, and` is positively arrested at the end of each operative cycle,

The accurately kmeasured'rotation of the driven disc 48 synchronism with the operation of the imprinting apparatus is transmitted through suitable. gear trainsto one or both pin type strip feeding and .elevatingdevicea one of which may be connected and disconnected at the Will ofthe operator. The transmission mechanism is Mbest illustrated in Figs. 5 to 11 inclusive. v

Thesideframe 2-3 of the super-structure is formed with an integral gear housing at itsouter side, which is divided by a vertical wall lil (Figs. S, 9, and l1) into .outer and inner compartments 'li and 72, the latter having an upward continuation 'i3 extending above the level of thecompartment li. The division Wall 7B Yprovides-.a series of bearings for various operating partsof the transmission mechanism. FiXedly 'secured to a reduced portionof the shaft 4l of the disc 43,

which extends through theframe member 23into the. gear vcompartment l2, which motion is transmitted to one set of feeding and elevating devices.V Detachably engageable with the reduced extremity of the shaft l by a f shiftab'le'clutch 75 is an'axially aligned continuation Thief the shaft lll'l driving a gear train transmittirtgV motion to the second set of feeding and elevating devices in timed sequence with operation .of the printing-mechanism andprimary lfeeding is a spur gear 74 by,

with by a clutch,

gear 63 is adjustably engaged by a variable 85 Qi conventional construction, such as customarily embodied in typewriters for rotatively adjusting the platen roll thereof relative to the line spacing mechanism.

This variable comprises a simple form of springV actuated clutch on the end of the shaft, Which upon axial retraction by a knob 8G may be-reengaged indifferent rotative relation of the shaft andV gear. The elevator shaft 21 being driven by the described gear train transmits unison'rotation to the shaft 23 of the pin type feeding-devices I6 through a substantially vertical shaft4 8l mounted in suitable brackets 33 on the outer side of the opposite frame memb er 22 of the super-structure, as shown particularly` in Fig. 3. The transmission shaft 87 carries at each-end bevel pinions 89 intermeshingfwith corresponding pinions 93 upon the respective shafts 2G aand 21which are thus intermittently actuated in unison throughmeasured range .,of. operation.

The second set-cf feeding ann` elevator devices are actuated simultaneously but ordinarily through ardifferent range of movement fromthe same initial shaft 49 on which is mounted the timing disc d8. The second train 'ofY transmission mechanism is illustrated in Figs. 5, 6, '7, 8, Band llfl The axially alignedl continuation 16 ofthe shaftV [il is releasably connected therel5 `Within the gear housing compartment l2. As shown in Fig. 8 and in enlarged detail in Fig. 18, the shaft continuation- 'iS-is providedwithan'enlarged counterbored head Si into which the reduced eXtremity of the yprirnary shaft fil projects. This head is longitudinally slotted at one side as is also the reduced rextremity of the shaft 4l. A peripherally groovedgclutch collar 'l5 slidingly mounted upontheshaft headill carries an inwardly projecting studV S2 engaging in the registering slots toicouple the shafts il and 'it for unison means, when-operatively connected with the driving means by adjustment of theclutch l5.

Referring particularly to Figs. 7 and 10, the 1 gear lll, which rotates inunison with therotary discl, intermeshes with agear 'Il journaled on a studV the 'upperextens-ionl'l' ofthe gear cornpartrnent l2; Detachalely connected Awith the gear T! for unison rotation is a gear pinion 18 lwhich is Ainterclfrangeable `with other gear pinions of different size for varying the speed and range of operati-on of the, driven mechanism.VV This interchangeable Vgear. pinionk 'i3 is retained yin driving engagement with the Ylarger .gear Tl by a slotted collar 845 having straddle engagement. in a peripheral groove'in the pinion shaft.

Intermeshing with the gear pinion 18 is an idler pinioni carried by an .oscillatory farm 82 .pivoted concentrically with a driven gear 535 With which the idler pinion 8l intermeshes. The swinging adjustment ofthe carrier .armacconnnodates the idler pinion to interchangeable pinions 'i8 Yof different size. The carrier .arm is ,releasably held in its adjusted position by a Aclamp bolt engaging through Van arcuate slet in the head of the carrier arm.

The .driven gear .S3 is mounted `on the .extremity of the upper `elevator shaft 21 which carries the upper pin type elevator 25 for feeding the original 1&3 carried by or form strip lil intothe `receiving tray 2:9. Y The T15 rotation. Vthe solid line to. the dotted line posi-tionof Fig.

The'crank shaft 93 and crank MJS make complete rotations, While the rocker arm It actuated thereby, being of greater. radius, is, moved t0 and fro through a limited oscillatorygmo-tion which is transmitted to the ,rock shaft IM.

The outer end of the rock shaft illl carries within the gear compartment 'il a small gear pinionli and closely adjacent thereto a gear appearance in 5, the gear pinion doesY not mesh with the gear pinion S1Y but is Yoiset inwardly of the plane of'the gears 96 andfl as shown in Fig. 8.v

yThe oscillatory gear elements |05' and |56 intermesh respectively with companion gear segments I-i and |63 of different radii, whichare mounted concentrically with each other in a bearing hub |59 projecting from the gear housing division Wall 1E! and about a rotary shaft H9. (See Fig. 9.) The gear sectors I'l and |58 are free for relative oscillatory motion independently of each other and independently of the intermittently actuated shaft Hil. Fixedly secured upon the outer end of the shaft l0 within the gear compartment 'II is a ratchet wheel i I I having in its periphery a succession of ratchet teeth and a succeeding segmental portion H2 which is devoid of teeth. The ratchet wheel lil has in its hubA H3 two ratchet teeth H4, disposed in approximately the same radial relation as the smooth or untoothed segmental portion H2 of the ratchet wheel III.

The purpose of this is toprovide for a differential feeding movement of the apparatus by y which a succession of relatively short advancev steps of the strip being fed will be followed by a longer advancement thereof. The duplicate or detail record strip II is divisible at'spacedrintervals upon transverse weakened lines into a succession of separate sheets. 1n imprinting the duplicate record a succession of imprinted leg# ends is effected at uniform line space intervals until the end of one of the sheet'sections defined by a transverse weakened line is reached. Thereupon the strip is advanced an increased distance at a single operation to accommodate a heading space upon the succeeding sheet siection and present the first imprint receiving position of such sheet in exact registry with the imprinting devices.

To effect .the successive line space feeding movements, the gear segment |51 .(front of |08) carries an outward projecting stud HE upon which is Apivoted a spring actuated paWl H5 having operative engagement with the teeth of the ratchet Wheel III. The rockingmotion of the shaft EM transmitted to the intermeshing gear segments |05 and |58 alternates the movement of the pawl H5 and thus Yadvances the ratchet wheel and with it the shaft H0 through successive relatively short partial Vrotations of equal extent. During this peri-od the intermeshinggear elements |535 and |88 also possess to and fro oscillatory motion in unison With the members m5 and It?. Being of different proportions, the resulting transmitted motion is of different degree' or extent.

Carried by the gear segment |88 is a Spring actuated pawl i It which rides idly upon the untoothed portion of the hub H3 duringthe step by step or line spacing movement of the ratchet wheel i i I under infiuence of the pawll l5. However, when the pawl H5 reaches the limit of the series of ratchet teeth in the wheelV I I, the teeth fifi in the hub H3 will have been moved into the range of action of the pawl H6, which by the oscillation of the intermeshing segments |06 and E53 is caused to engage the tooth H4 and move the ratchet Wheel and with it the shaft I I0 a longer advance step. This advancement effected by engagement of the pawl H6 upon the' segment |08 with the tooth H4 in the hub H3 of the ratchet wheel III is sufficient to advance the duplicate record strip H from the last imprint line of one detachable sheet section to the nrst imprint line of the succeeding sheet section, passing over'the heading space of such second sheet section, all in one'continuous movement. It also advances the ratchet wheel I I I sufficiently to carry the untoothed segment H2 beyond the paWl H5 which thereupon again engages its ratchet teeth. Thus, there are'two degrees of successive partial rotation transmitted to the shaft iii), including a` succession of short equal line spacing movements incident to the action of the pawi H5 upon the ratchet wheel III followed by a longer movement at the completion of a predetermined number of short steps, by the action of the pawl H5 upon the hub tooth H4 of the ratchetl wheel.

-At its inner end the shaft HE) carries within the compartment 'I2 a ratchet wheel H1, with which a spring actuated detent pawl I I8 engages to retain the Wheel and shaft in their advanced position of rotation and prevent back lash. This ratchet couple shown in Fig.` 6 is merely retaining means. However, secured to the inner end of the shaft H0 adjacent to the ratchet wheel Hl is a gear wheel H9 which intermeshes with a smallf gear pinion |20 upon the elevator shaft 8 which carries the pin type elevator device 26 having engagement in the marginal holes of the duplicate strip II and by which it is advanced over the deck 3|?.

Like the shafts 28 and 2l, the shaft 21 is operatively connected with the feed device shaft 20 as shown in Fig. 3 by a substantially vertical shaft |2| mounted in brackets |22 on the end frame 22 and'having at each end bevel gears |23 meshing with like gears |24 on the respective shafts 2| and 28. Unison timed movements of measured extent are transmitted by the mechanism described simultaneously to feeding and strip elevating devices 'I6 and 25.

feeding and elevating purposes,V including cooperating frictional rollers such as have been commonly used in the typewriter, autographic register and tabulating machine arts, the feeding and elevating devices as before-mentioned are preferably, although not necessarily, pin type feeding devices progressively engageable in successions of marginally punched holes in the record strips or engageable in more widely separated longitudinally spaced holes medially of strips. Such pin type feeding means may comprise pin wheels having relatively fixed feeding pins, traveling endless studded belts of reciprocatory pin feeders, of which there are numerous prior` art examples. However, the pin type feeding units shown in the drawings are of the reciprocatory pin style which forms the subject matter of Letters Patent No. 2,000,649 and No. 2,000,651, of May 5, 1935, to which reference is made, the specific construction and operation of which forming no part per se of the present invention and is not here described. Inasmuch as the record strips engage vthe feeding and elevating units IS, I1, 25 and 26 through only a relatively small segmental arca, retractable feeding pins are not essential and other forms of pin feed units may be employed.

The feeding and elevating units are mounted in spaced relation upon their respective shafts 29, 2|, 21 and 28 to agree With the Widths of the respective strips l0 and Il of record material,

While any Y suitable feeding means may be employed for strip which may lbe of fthe 'sameor ``dilierent width-s.

In operation, the respective driving motors of .the 'imprinting apparatus and the strip'feeding mechanism being set in operation, the Astri-ps IU and H are progressively automatically Withdrawn from the supply l2 and I3 and advanced past the numbering devices M 'and i5 which `are tripped by the oscillation lof 'the switch arm -BS o' the vcontrol switch t?? by `engageanent therewith iof .the stud fr? as the presser head -descende to imprint a previously numbered form which has been advanced past the numbering position into 'the printing vposition oy preceding opera-tions.

Thus, the feeding operation is d heen latter isdependent upon presentation oi tl 'end determining element inproper position. n'o legend determining member is supplied, there can be n'o'irnprinting, and without the imprint-- in'g operation fno feeding mo'vement occurs Thus, these successive operations mutually interdependent upon each other. The strips IS 'andi beihgadvanced past the imprinting po- 'sit'on "in superposed relation with a portion of carbon or transfer material. interleaved therebetween are .separately engaged, each by its own feedingdevice V'The overlying duplicate record strip 'H is engaged loy lthe feeding unit l?, While the original record strip 'l0 is engaged by the feeding u-nit ITS positioned in the rear of the unit T1 and on level therewith. These units are sub stantially tangential to the path of travel ci the strips'past the imprinting position,

The original record stripY lilV passes `from feeding unit l5 upwardly about a freely rotatingguide roller 6i Vthrough an opening in the trulnnion-boss 6i, of Which the link cf the magnetically operated tripping `device extends. The original record stri-p passesV thence over elevator unitl 25, which is substantially' identical Withthe .feeding units is and Il, and into the receiving lcomfpartrnent or tray 2S, The strip having been sharply folded in zigzag iform in the supply packet automatically reassuines such folded form as it enters the r calvin-g tray.

At the same time, the duplicate record strip l1, being 'advanced past imprinting petit-cn by the feed-ing units I?, vis directed upwardly 'about 'anlidier guide roller H Sto the elevator pun @hed units 26, by which the strip Il and accompanying carbon strip are discharged onto the decl: 3Q. The record strip passing beyond the deck 3Q is received in the tray 32 at the iront oi the machine, where it also reassumes its original fold lines. rThe carbon strip may be refolded with the strip Il, but is preferably diverted into a separate waste receptacle as the strips leave the deck 3G.

As before described, the feeding moveL lent of strips and the operation of the numbering device are electrically controlled by the movement of the presser head 9 to eiect an imprint impression on the positioned strips- The electrical control system is diagrammatically illustrated in Fig. 25. As there illustrated, the electrical service or power lines 35 communicate with a switch block 13e located on theback of the machine as shown in Figs. 3, 4, land 10. included in this switch unit are several manually o erated switches, one of which (lB'l) controls the l tor cable 38 supplying energizing current to the actuating motor 35 which drives the strip feeding apparatus independently of the inlprinting mechanism. I

A second manual switch i539 of the same unit ISE is connected in series with the automatically operated switch 65 in the circuit et by which the numbering units are actuated. The numbering devices le and I5 are preferably commercial electrically operated units, which embody electromagnetic means or a solenoid through which the circuit isl intermittentli7 closed in timedl sequence by the closing of the switch 55. This switch, together with the companion switch il controlling the mechanism tripping solenoid 6E, is tripped in proper sequence by the engagement of the stud 65 carried by the lever 64- on the printing head S (Figs. 20 and 21) with the oscillatory trip levers 5t and 63, pertaining respectively to the switches el and E@ as shown in Fig. 4.k The automatic switch 61 is in series with a manual switchl of the switch unit 35 and serves to intermittently energize .the feed mechanism tripping magnet or solenoid Gli. The solenoid 6E, as before dcscrib-ed, is connected through the link 59 with the trip lever 52 (Figs, 12 to 15), the oscillation of whicli permits the driver dog 53 to fall into clutch engagement with the notched disc 49 to enable the constantly running motor 35 to actuate the strip feeding mechanism through one complete cycle at the end of which the clutch dog is automatically withdrawn. y.

To prevent sparking, condensers lei are bridged across the automatic switches E5 and 61. To protect the numbering units le and l5 against damage, thermal overload circuit breakers H52 are interposed in the electrical energizing circuits thereto. Furthermore, to enable the operation of either of the numbering devices without the other, additional manually operated switches H53 are provided in each of the numbering unit circuits.

Interposed in the circuit 69' in series with the switch 66 is an additional listing make and break switch 43. This is adapted to be actuated by a contact roller |114 on an arm M5 carried by the rotating shaft lill. The shaft IIO rotates once for each succeeding form to be imprinted.

A screw Ifif on the listing switch [43 may be adjusted at will to hold the switch closed independently of its actuation by the arm leo. If it is desired to imprint on every line or at every sucoeedingimpression regardless of how many impressions may be made within a given length of strip or on a single successive form, then the switch E43 is permanently closed by adjustment of the screw Mii. Thereupon the switch GS, which is actuated at every movement of the printing head, by engagement of the stud with the trip lever 69, correspondingly actuates the numbering device i4 or l5, or both, repeatedly. However, if but one numbering operation is effected for each form or given length of strip, then the screw ifi, being relieved, allows the switch i513 to open. rEhereafter, it is closed intermittently by the rotating arm i555 by the shaft lle which-at intervals occurs simultaneously with the closing of the switch Gt by the stud G5, but not every time' the' switch 66 is closed. So long as the switch M3 is operative and stands open, the switch 6'3 may be repeatedly closed idly with each impression without operating the numbering device. However, when the arm E55 closes the'switch M3 simultaneously with the closing of the switch 65 by the imprinting head, Athe numbering device will be operated. For example, in a particular installation the continuous series connected record forms are adapted to receive twenty successive line spaced impressions. If it is desired to number each line impression, the screw' M5 being tightened to permanently close the switch M3, the switch GGoperates every time an impression is made to energize the numbering device. However, with the screw M5 relieved, the switch 143 is operated by the arm IE5 only each twentieth time, i. e., but once for each form length.

From the above description it will be apparent that there is thus provided a device of the character described possessing' the particular features of advantage before enumerated as desirable, but which obviously is susceptible of modification in its form, proportions,-detail construction and arrangement of parts without departing from the principle involved or sacriiicing any of its advantages. g
